Benefits of technology

[0009]To achieve the above object, a card connector comprises an insulating housing; a plurality of contacts retained in the insulating housing and a shell. The shell covers the insulating housing to define a card receiving space therebetween and defines a card insertion direction. The contacts comprise a plurality of contacting portions exposed into the card receiving space. A stopper is formed on the shell and protruding into the card receiving space and comprises a stopping portion approximately uprightly exposed into the card receiving space along the card insertion direction to prevent the card from mis-insertion.

Problems solved by technology

However, a user may insert the electrical card into the card connector in an improper state by mistake.
In this situation, the card connector, the electrical card and even the electronic appliance may be damaged.
When the card is properly inserted, the stopper will be accommodated in a slot formed in the card and does not prevent the card from inserting into the card connector to electrically connect with the contacts.
However, because the stopper uprightly arranges along the transverse direction, intensity of the stopper is weakened.
When the card is improper inserted some times by mistake, the stopper may be deflected from an original position due to collision of the card and does not prevent the card from electrically connecting with the contacts.

Abstract

A card connector (1) includes an insulating housing (2); a number of contacts (3) retained in the insulating housing (2) and a shell (4). The shell (4) covers the insulating housing (2) to define a card receiving space therebetween and defines a card insertion direction. The contacts (3) comprise a number of contacting portions (32) exposed into the card receiving space. A stopper (44) is formed on the shell (4) and protruding into the card receiving space and comprises a stopping portion (440) approximately uprightly exposed into the card receiving space along the card insertion direction to prevent the card from mis-insertion.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention is generally related to a card connector, and especially to a card connector with an anti-mismating device.[0003]2. Description of Related Art[0004]With the development of electronic appliances, different electrical cards are used to expand additional functions of the electronic appliance, such as data storage. A card connector is required to receive the electrical card to achieve the storage function between the electrical card and the corresponding electronic appliance. However, a user may insert the electrical card into the card connector in an improper state by mistake. In this situation, the card connector, the electrical card and even the electronic appliance may be damaged. Thus, one way to solve the above mention problem is to design the card connector with an anti-mismating device.[0005]A common card connector adapted for receiving a card comprises an insulating housing, a plurality of con...
